  • the kit preferably contains the desired liquid cleanser and/or other active material, in its own container.
  • the active material may be substantially dry and impregnated into or deposited onto the film as disclosed in, for example, United States Patent No.: 5,980,931.
  • the active material may be placed in at least one enclosure attached, either fixedly or removably, to the textured film, the securing means, and/or the holding means.
  • the enclosure is attached to the textured film and, for the spherical textured film device 10, located in the center 30 of the device 10.
  • the enclosure may be comprised of any material capable of enabling the transport of the primary agent from within the enclosure to outside of the enclosure at a desired time.
  • the enclosure has walls comprised of either a water soluble material or a water insoluble material.
  • suitable water soluble materials include, for example, water soluble films such as polyvinyl alcohol, cellulose derivatives such as methylcellulose, hydroxyethylcellulose, carboxymethylcellulose, gelatin, and those disclosed in Davidson, Robert L., et al., "Water Soluble Resins," Chapters 2 - 9 (1968).
  • the thickness of the water soluble film may range from about 0.01 mm to about 0.08 mm, and preferably from about 0.025 mm to about 0.05 mm.
  • the active material may be dispensed from the enclosure having walls comprised of water soluble materials by wetting the device with a sufficient amount of water needed to solubilize the walls.
  • the enclosure may possess walls comprised of a water insoluble film including, but not limited to polyvinyl chloride, polyvinylidine chloride, polyethylene, polypropylene, vinyl chloride copolymers, ethylene vinyl alcohol, and mixtures thereof.
  • the thickness of the water insoluble film may range from about 0.01 mm to about 0.08 mm, and preferably from about 0.025 mm to about 0.05 mm.
  • the active material may be dispensed therefrom by applying pressure to the enclosure in order to puncture the water insoluble film membrane.
  • the enclosure may be a container comprised of water insoluble material, wherein the walls of the container have a general thickness of from about 0.025 mm to about 3 mm, preferably from about 0.25 mm to about 1 mm.
  • Such containers may be replaceable or refillable.
  • the active material may be dispensed from such containers through at least one capped and/or valved dispensing hole in at least one wall of the container. Upon removal of the cap, the active material may be dispensed from the container.
  • the valve which may be activated by squeezing the walls of the container or by manually deflecting a member of the valve, may be in the form of a slitted membrane, ball and spring, duckbill, or any other valve known in the art of dispensing containers. See, e.g., United States Patent Nos.: 4,728,006, 4,782,975, 5,632,420, 5,680,969, 5,079,013, and French Patent No. 1,364,891.
  • the cross-sectional shapes of the perforated films were film-like in appearance.
  • the netted mesh had individual strands of filaments having a cross-sectional shape that ranged from nearly round to kidney-shaped.
  • the cross-sectional view of the netted mesh sections at locations where the strands were joined together appeared to have a "dog-bone” or "dumbbell"-like shape.
  • a 20 cm x 200 cm sheet of the film available from Tredegar Film Products, Inc. under the tradename, "VISPORE®” and having an open area of about 14% was folded back and forth upon itself in accordance with the method illustrated in FIG. 13 in order to form a corrugated structure having a height of about 3 cm. After tying the structure in the center with a conventional rubber band, a round, almost spherical implement resulted.
  • the structure produced a significant amount of aesthetically-pleasing lather and effectively and gently cleaned the skin without irritation. Moreover, the users remarked that the structure was soft and non-irritating to the skin.
  • This Example showed that the novel structure containing a known shower gel was capable of producing a significant amount of lather without irritating the skin.
  • Example 3 Lather Comparison - Diamond Mesh Puff Versus Perforated Film Device
  • Example 2 Five devices, which were comprised of the film described in Example 2 were produced in accordance with the procedure set forth in Example 2. A second set of five devices were similarly made, but using a similar film having a 4.2 % open area.
  • each subject After applying 2 ml of a shower bath available from Johnson & Johnson Ltd. under the tradename, "pH 5.5 Body Wash" to each respective wetted forearm, each subject then independently rubbed a device of this example along the forearm to create a lather for about 30 seconds. Each respective device was then squeezed, and the lather produced therein was collected in an independent graduated cylinder in order to measure the foam volume.
  • This Example showed that foam volume and quality were not sacrificed by the soft gentle cleansing offered by the puff of the present invention. Moreover, this Example showed that more lather is produced by perforated film puffs having a larger open area relative to those having a relatively smaller open area. In addition, this Example also showed that perforated film puffs, which have a lower overall open area than that of diamond mesh puffs, produced a significantly larger amount of lather relative to the diamond mesh puffs.
